Dennon RC 1156 has stopped controlling the Dennon AVR 3312 receiver. I have pointed a Camera to the lens of the Remote and I am able to see the light responding to the buttons on the remote. Can anyone help
While you would lose all of your settings, I would recommend trying a Microprocessor Reset. Before doing this, I would unplug the Denon from the wall, etc. I forgot the procedure for Denon, but it invariably involves holding down a combination of 2 buttons on the front panel of the Denon.
